What H1 points to
A Samsung washer showing H1 has found a problem with water temperature. Machines from an earlier generation show the same fault as HE. H1 itself is a current code, listed beside legacy ones, and the meaning may differ by model.
What the manual says
Only one instruction accompanies the code: call Samsung customer support. The text lists no reset and no hose check for it.
Other codes to look at
HOT means the machine is too hot, which is not a fault.
Anyone in San Francisco or the Bay Area with a water temperature code can use Samsung washer repair or dial (415) 969-6153. Have H1 on hand along with the model number and a note of when it appears.
Model compatibility: Samsung reuses codes across series and model years, so H1 Water temperature issue may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
